Answer»

The reaction of hydrogen and iodine monochloride is given as:
$H_{2} (g) + 2 I C l (g) \to 2 H C l (g) + I_{2} (g)$

This reaction is of first order with respect to $H_{2} (g)$ and $I C l (g)$ , following mechanisms were proposed :
Mechanism A : $H_{2} (g) + 2 I C l (g) \to 2 H C l (g) + I_{2} (g)$

Mechanism B : $H_{2} (g) + I C l (g) \to H C l (g) + H I (g), s l o w$

$H I (g) + I C l (g) \to H C l (g) + I_{2} (g), f a s t$
Which of the above mechanism(s) can be consistent with the given information about the reaction?
